摘要
采用乙醇三氯甲烷(2∶1) 作溶剂,对选定的30 种中草药粉末进行提取,测定各种提取物的抗氧化活性,用烘箱法和OSI法两种方法测定的结果表明厚朴、射干、甘草、芡实4种中草药提取物具有明显的抗氧化活性.山楂、虎杖、白药子、千斤拔、八角在烘箱法测定中表现抗氧化活性较强,而OSI法测定的抗氧化活性较弱;相反,诃子等在OSI法测定中表现抗氧化活性较强,而烘箱法测定其抗氧化活性较弱.
The thirty Chinese medicines powder are extracted with ethanol?chloroform(2?1)solvent. Determinating antioxidant activity of these extraction with oven method and OSI. The results indicated that four Chinese medicines: Magnolia officinlis, Belancanda chnesis, Glycyrrhiza uralensis, Euryale ferox have strong antioxidant activity. Others have weaker than those. The antioxidant activity of Belancanda chnesis is first reported.
